* Replace the `Match` interface with `ParametersMatch`, to avoid parse errors due to `match` being a reserved keyword in PHP 8.
* Replace `ReflectionParameter::getClass()` usage, which is deprecated in PHP 8.
This allows tests relying on the `getMockForAbstractClass()` and `getMockBuilder()` methods to run again on PHP 8.
When the test suite is updated for compatibility with PHPUnit 9.x, these overrides can be removed.
Follow-up to [48972].
